My mistake was to call a big plumbing company - their plumber could not install my new faucets without leaks. I went to get new supply lines and still he installed it and there were leaks. They charge me $286.00 for no satisfaction.
Then, Mike from AAA Advanced Plumbing came. In 15 minutes, the faucets were installed - worked perfectly. Mike came on time, did the work professionally and quickly.
His service call of $125 was covered by the plumbing supply company who was mortified that the faucet might have been defective. Obviously big companies do not always employ the best workers! From now on, to get the job done right, I will call AAA Advanced Plumbing first!
